DETAILED DESCRIPTION OF PREFERRED EMBODIMENT

Turning now to the drawings, FIG. 1 shows a configuration of a contemporary computer and its peripheral devices. A monitor 20, one of the peripheral devices of a computer 10, can display characters or picture which can be recognized by a user. This is done according to the signal transmitted from the computer 10. A key board 30 has a number of keys each having its own inherent signal content. Thus, if each key is input, the computer 10 performs an operation corresponding to the input key signal. A mouse 40 is one of the input devices for inputting signals to the computer 10. Likewise, the key board 30 can be used for inputting. In a contemporary practice, a number of tune keys are installed in one side of the monitor to tune the image or color of the picture displayed on the monitor. However, the number of the tune keys which can be installed in the monitor is limited.

Referring now to FIGS. 2 to 4, various monitor control devices according to the principles of the present invention constructed with a key board 30 and a mouse 40 that are separated from a computer 10 and can be remote-controlled. A remote-control signal receiving unit (not shown) is installed in one side of the front of the monitor, to receive the remote-control signals generated from the key board 30 and mouse 40. Referring to FIG. 3, the key board 30 and mouse 40 are not connected to the computer 10 but to the monitor 20, and two signal transmission lines are connected between the monitor 20 and the computer 10. Referring to FIG. 4, the key board 30 and mouse 40 separated from the computer 10 are connected to the monitor 20 via a controller 50.

As described above, the key board 30 and mouse 40 of the computer peripheral device are connected to the monitor 20 in various form and transmit signals. The signals are transmitted to the monitor 20 to control the monitor 20 or to the computer 10. In this case, the important feature is that the peripheral device (key board and mouse) is not connected to the computer but to the monitor. In addition, the signal generated from the computer peripheral device is determined whether it is a monitor control signal or a computer transmission signal. The controller 50 for generating a corresponding control signal according to the determination is installed inside or outside of the monitor 20.

The operation of the monitor control device according to the present invention will be discussed hereinbelow.

Referring to FIG. 2, the key board 30 which can be remote-controlled generates a signal by combination of several keys. The mouse 40 generates a signal by combination of the mouse buttons at the right and left or center thereof This generated signal is outputted via a remote-control signal transmitting unit (not shown), such as located in mouse 40. The signal output via the remote-control signal transmitting unit is transmitted to a remote-control signal receiving unit (not shown) installed in one side of the monitor 20. Thereafter, this signal is transmitted to a signal receiving unit of the controller 50 in monitor 20, for example. A signal interpreting unit determines whether the transmitted signal is a monitor control signal or an information signal to be transmitted to the computer. According thereto, a corresponding signal is generated. The control signal is transmitted to the monitor 20 and computer 10 by the signal transmitting unit of the controller 50.

In FIG. 3, the key board 30 and mouse 40 are separated from the computer 10 but connected to the monitor 20 via the transmission line, as compared with FIG. 2. Thus, the generated signal is processed by the controller 50 installed in the monitor 20.

In FIG. 4, the controller 50 is placed at the exterior of the monitor 20, thus forming a signal transmission system of the key board 30 and mouse 40 and the monitor 20.

Even though the configuration of these monitor control devices are somewhat different one to another, the operating principles thereof are similar to each other. The operation of these constructions will be discussed with reference to accompanying flow sheets shown in FIGS. 5 through 8, inclusive.

FIG. 5 shows the operating steps of the controller 50 of FIG. 4. If a signal is input at S51, the controller 50 checks an address first at S52. If the address is its own address at S53, i.e. a monitor control signal, the controller 50 performs the command at S54. If the address is not its own address, it is transmitted to the computer at S55.

FIG. 6 shows an internal configuration of the monitor including controller 50 to which the present invention is applied. The input signal receiving unit 640 receives a signal from the key board, mouse or the remote-controlled key board or mouse; hence the input unit 650 of FIG. 6 can be a keyboard 30 or a mouse 40. The controller 630 interprets the signal transmitted via the input signal receiving unit, such as a monitor control signal to be transmitted to a monitor or an information signal to be transmitted to the computer, and then performs the command. The signal transmitting unit 620 respectively transmits the input signal or the command result of the controller to the computer 610 or to the monitor 20.

The operation of the present invention will be discussed with reference to the flow sheet of FIG. 7. If a signal is input, the controller of the monitor checks in step S1 if an environment of the monitor has been set. If the environment has not been set, the controller checks in step S7 if the input signal is an environment set signal. If the input signal is an environment set signal, the controller sets the environment of the monitor in step S8, and if not, transmits the signal to the computer in step S9. If it is checked in step S1 that the environment has been set, the controller checks in step S2 if the input signal is an environment reset signal. If the input signal is an environment reset signal, the controller resets the environment in step S3 and if not, interprets the command in step S4. After the interpretation, the controller determines if the command needs to be transmitted to the computer in step S5 and then transmits it to the computer in step S6 or completes the procedure.

Meanwhile, the monitor can transmit various data of the computer peripheral device to the computer by using a specific input signal, and the operating procedure thereof will be discussed hereinbelow with reference to the flow chart of FIG. 8. The procedure is performed on the assumption that a specific software must be previously driven in step S20 before transmitting an EDID (Extended Display Identification Data). With this software, the computer can perceive that the data to be input thereafter is the EDID. After execution of the software, the user transmits a monitor environment setting signal to the monitor by using the key board or the mouse in step S30. Thereafter, the user transmits the command for transmitting the EDID in step S40. After receiving this command, the monitor transmits the EDID to the computer in step S50. After receiving all EDID, the computer displays a signal receiving completion message on the monitor in step S60. The user transmits an environment reset signal to the monitor by using the key board or the mouse in step S70.

In summary, the present invention includes the steps of receiving the signal generated by the computer peripheral device at the signal receiving unit in the monitor; interpreting the received signal to determine whether it is a signal for controlling the monitor or a signal to be transmitted to the computer; and if the received signal is a signal for controlling the monitor, outputting the monitor control signal and if the received signal is a signal for controlling the computer, outputting the computer control signal to the computer via the transmission line.

In addition, the method of transmitting the monitor setting state to the monitor and resetting the monitor state has the steps of transmitting a monitor setting start signal via the computer peripheral device connected to the monitor; transmitting data on the setting state of the monitor to the computer via the transmission line connected to the computer; displaying a signal receiving completion message by the computer after receiving the data on the monitor; and transmitting a monitor environment reset command to the monitor by using the computer peripheral device to reset the environment of the monitor.

As described above, without using several tune switches installed in outer surface of the monitor, the present invention can achieve the same effect as the case of using them. That is, the monitor can be controlled by connecting the computer peripheral device thereto, without the use of the tune switches. Thereby, the manufacturing costs and additional steps required in manufacturing can be remarkably reduced. Further, it is possible to control the power by adjusting the power switch of the monitor and computer, using the transmission line connected between the monitor and the computer.

It will be apparent to those skilled in the art that various modifications and variations can be made in the monitor control device of the present invention without departing from the spirit or scope of the invention. Thus, it is intended that the present invention cover the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
